Description

The present invention relates to a wall panel connecting structure in which vertical frames of wall panels on the upper and lower floors of a building such as a house are connected to each other.

For example, a steel house is known as a building constructed by a frame wall construction method. In this steel house, the wall body is composed of a plurality of wall panels. This wall panel has, for example, a frame body composed of a pair of upper and lower horizontal frame materials and a plurality of vertical frame materials provided between the horizontal frame materials, and the wall surface materials are fixed on both sides of the frame body. It is configured to be.

Such wall panels are arranged by sandwiching the floor panels constituting the floor at the top and bottom, and are connected by connecting metal fittings.
As an example of the connecting metal fitting, the one described in Patent Document 1 is known. This connecting metal fitting is called a bypass hardware. The bypass hardware is provided with a bolt having a length that can be arranged vertically across the vertical frame material of the wall panel on the upper floor and the vertical frame material of the wall panel on the lower floor, and is provided with a bolt in the axial direction of the bolt. Side opening groove-shaped joint metal fittings arranged on the upper floor side and lower floor side at intervals and fixed to the vertical frame material of the wall panel of each floor are arranged respectively, and the side opening groove in each joint metal fitting. The bolt is detachably fitted to the bolt, and the metal joint is attached so that the position can be fixed in the longitudinal direction of the bolt.

However, in the former building described above, that is, in a building in which the wall panels on the upper and lower floors are connected by connecting metal fittings, since the wall panels are separate bodies, a significant improvement in the bonding strength of the connecting portion between the wall panels cannot be expected. Therefore, when a seismic force is applied to the building, a pulling force acts on the vertical frame material of the wall panel, and there is a possibility that the vertical frame material may be lifted and deformed. In some cases, when the floating deformation occurs, a rotational force acts on the wall panel, which may cause the building to collapse.
Further, in the latter building described above, there is a problem that a large through panel is required, which requires time and effort for on-site construction. Such a problem becomes more prominent as the height of the building increases, and it is extremely difficult to apply it to a three-story or four-story building.

The present invention has been made in view of the above circumstances, and provides a wall panel connecting structure capable of suppressing floating deformation of a vertical frame material of a wall panel in the event of an earthquake or the like and facilitating on-site construction. It is an object.

In order to achieve the above object, the wall panel connecting structure of the present invention is a wall panel connecting structure in which the vertical frame members of the wall panels on the upper and lower floors of a building are connected by connecting metal fittings.
A through material extending vertically and having an upper end bonded to the superstructure material of the building and having a lower end bonded to the foundation of the building is provided so as to be separated from the wall panel.
It is characterized in that the vertical frame material of the wall panel on each floor of the building and the through material are connected by an oblique material inclined with respect to the horizontal.

In the present invention, since the vertical frame material of the wall panel on each floor of the building and the through material are connected by a diagonal material inclined with respect to the horizontal, the vertical frame material has a pulling force in the event of an earthquake or the like. When acting, this pulling force can be transmitted to the lumber through the diagonal lumber. Therefore, it is possible to suppress the floating deformation of the vertical frame material.
In addition, at the site, the upper end of the through material may be connected to the superstructure material, the lower end may be connected to the foundation, and the vertical frame material and the through material of the wall panel on each floor may be connected by diagonal materials, which is large. Since there is no need for a through panel, there is no need to transport large parts from the factory, and on-site construction is easy.
Further, by reducing the axial force acting on the connecting metal fittings that join the wall panels on the upper and lower floors, it is possible to reduce the size of the connecting metal fittings installed inside the wall panels.

Further, in the configuration of the present invention, it is preferable that the joint portion between the vertical frame material and the diagonal member is arranged within the upper and lower ranges of the vertical frame material provided with the connecting metal fittings.

According to such a configuration, since the joint portion between the vertical frame member and the diagonal member is arranged within the vertical range of the vertical frame member provided with the connecting metal fitting, the vertical frame member of the diagonal member is arranged. The joint to the lumber can be stiffened by the connecting metal fittings. Therefore, it is possible to prevent local damage to the vertical frame member due to the load acting on the vertical frame member from the diagonal member.

Further, in the configuration of the present invention, it is preferable that the threading material has the same cross section over the material length.

Here, the fact that the threading material has the same cross section over its entire length means that the threading material is insufficient in length, so when the threading material is joined (longitudinal) in the axial direction (longitudinal direction), the joining is concerned. It means that the threading material has the same cross section over the entire length except for the portion (longitudinal portion).

According to such a configuration, since the through material has the same cross section over the length of the material, it is possible to prevent axial deformation of the through material between floors. In addition, the through material can be joined without using a plate for adjusting the plate thickness such as a splice plate at the vertical joint portion of the through material, which leads to improvement in workability.
In addition, by consolidating the member cross sections of the through material into one specification, it is possible to surely prevent the members from being misplaced during construction and reduce the management load of construction.

According to the present invention, it is possible to suppress the floating deformation of the vertical frame material of the wall panel in the event of an earthquake or the like, and it is easy to construct on-site.

It does not occur. Therefore, even if the through columns 15 and 15 are joined (longitudinal joint), the axial force can be reliably transmitted.

As shown in FIG. 3A, the vertical joint portion 45 between the vertically adjacent through pillars 15 and 15 is from a portion where the tip end portion of the floor panel 12 is connected to the through pillar 15 via the gusset plate 14. It is located above. That is, the vertically adjacent through columns 15 and 15 are vertically connected at a position above the floor panel 12. Therefore, since the floor panel 12 does not get in the way during the vertical joint, the vertical joint between the through columns 15 and 15 can be easily performed.

Further, the longitudinal joint portion 45 between the vertically adjacent through columns 15 and 15 may be configured as follows, for example. That is, as shown in FIG. 10, the splice plate 55 straddles the joint ends of the channel steels 15a and 15a inside the channel steels 15a and 15a of the vertically adjacent through columns 15 and 15.

In, a gusset plate 23 that connects the upper end portion of the diagonal member 22 to the upper end portion of the frame member 21 is arranged within the range L of the vertical length of the lower fixing member 28.

As described above, according to the present embodiment, the vertical frame material 21 of the wall panel 11 on each floor of the building and the through pillar (through material) 15 are connected by the diagonal material 22 inclined with respect to the horizontal. Therefore, when a pulling force acts on the vertical frame member 21 in the event of an earthquake or the like, this pulling force can be transmitted to the through column 15 via the diagonal member 22. Therefore, it is possible to suppress the floating deformation of the vertical frame member 21.
At the site, the upper end of the through pillar 15 is connected to the superstructure material such as the roof panel 13, the lower end is connected to the foundation 16, and the vertical frame material 21 and the through pillar 15 of the wall panel 11 on each floor are diagonally connected. Since it is sufficient to connect by the material 22, a large through panel is not required, so that it is not necessary to transport a large member from the factory, and the construction on site becomes easy.
Further, by reducing the axial force acting on the connecting metal fitting 26, the size of the connecting metal fitting 26 can be reduced.

Further, since the joint portion (gusset plate 23) between the vertical frame member 21 and the diagonal member 22 is arranged within the vertical range in which the connecting metal fitting 26 is provided, the vertical frame member 15 of the diagonal member 22 is provided. The joint portion of the above can be stiffened by the connecting metal fitting 26. Therefore, it is possible to prevent local damage to the vertical frame member 21 due to the load acting on the vertical frame member 15 from the diagonal member 22.
In addition, since the through pillar 15 has the same cross section over the material length except for the joint portion (longitudinal joint portion 45) between the through pillars 15 and 15 adjacent to each other in the vertical direction, the axis between the floors of the through pillar 15 Directional deformation can be prevented. Further, the through pillar 15 can be joined without using a plate for adjusting the plate thickness such as a splice plate for the vertical joint portion 45 of the through pillar 15, which leads to improvement in workability.

A comparison of horizontal displacements was carried out by numerical analysis when a layer shear force F assuming that the horizontal force distribution input to each layer due to an earthquake was formed into a triangular shape was applied to the wall (FIG. 12 (b)). The effect of the invention was verified. The through pillar 15 and the vertical frame member 21 of the wall panel W are connected by an oblique member 22.

For the wall panel W, a panel member having a steel face material commonly used in the current steel house is assumed, and for the through material 15 and the diagonal material 22, C-100 × 50 × 15 × 2. It is assumed that the assembly material is made by assembling two channel steels with lips back to back. The cross-sectional terms of each member are as shown in Table 1.

The results are shown in FIG. In the graph shown in FIG. 13, the vertical axis shows the floor height of the building, and the horizontal axis shows the horizontal displacement amount (mm) in each layer.
As shown in FIG. 13, an increase in rigidity can be confirmed in the building provided with the wall panel connecting structure (including the wall panel) according to the present invention, as opposed to the building provided with the existing wall panel (conventional structure). It was found that in the main structure having the same strength as the building equipped with the wall panel structure, the horizontal displacement of each layer can be suppressed by 15% to 38% with the same strength, and the main structure by the wall panel connection structure according to the present invention. The effect of increasing the rigidity of the body was confirmed.
